      "撤销某个特定的提交，并通过创建一个新的提交来记录这次撤销。"
    ],
    "correctAnswerIndex": 1,
    "explanation": "`git cherry-pick`允许开发者挑选一个或多个特定的提交，并将其“移植”到当前所在的分支上，而不是合并整个分支的所有内容。这在需要将特定修复或功能快速应用到其他分支时非常有用。",
    "source": "文档中「1.1 Cherry-pick 是什么？」部分",
    "hint": "文档中描述该命令“允许我们选择性地将某个提交（ts）应用到当前分支”。"
  },
  {
    "question": "当你使用`git revert`撤销一个提交时，它对Git的提交历史有什么影响？",
    "options": [
      "它会直接删除目标提交及其之后的所有提交。",
      "它会将分支指针移动到目标提交之前的状态，但保留工作区的修改。",
      "它会创建一个全新的提交，这个新提交的内容是目标提交的逆向操作，从而保留了原始的提交历史。",
      "它会修改目标提交的内容，但保留其提交哈希值。"
    ],
    "correctAnswerIndex": 2,
    "explanation": "与`git reset`不同，`git revert`不会修改或删除历史记录。相反，它通过创建一个新的、反向的提交来撤销指定提交的更改。这样做的好处是保留了完整的项目历史，对于已经推送到共享仓库的提交来说是更安全的操作。",
    "source": "文档中「2.1 Revert 是什么？」部分",
    "hint": "思考`revert`和`reset`在处理历史记录上的根本区别，文档提到`revert`“并不会改变 Git 历史”。"

      "--soft",
      "--hard",
      "--continue",
      "--mixed"
    ],
    "correctAnswerIndex": 1,
    "explanation": "`git reset --hard <commit>` 会将HEAD指针、暂存区和工作区全部重置到指定提交的状态。这意味着任何在指定提交之后进行的修改（包括已暂存和未暂存的）都将被永久删除，因此这是一个需要谨慎使用的“危险”操作。",
    "source": "文档中「3.3 Reset 的常用选项」部分",
    "hint": "文档中强调这个选项应该“慎用”，因为它会“完全回到指定的提交状态”。"
  },

      "git revert",
      "git cherry-pick",
      "git merge"
    ],
    "correctAnswerIndex": 1,
    "explanation": "`git reset --hard`会改写历史，如果该历史已经被推送到共享仓库，强制推送会给其他团队成员带来巨大的麻烦。而`git revert`通过创建一个新的提交来撤销更改，这是一种非破坏性的操作，它清晰地记录了撤销行为，并且可以安全地推送到共享仓库。",
    "source": "文档中「二、Revert —— 撤销指定提交」和「三、Reset —— 回退到指定提交」部分的对比理解",
    "hint": "哪个命令通过“创建新的提交”来撤销更改，而不是“改变历史”？"

    "question": "如果你执行了`git reset --soft <commit-hash>`命令，将会发生什么？",
    "options": [
      "分支的HEAD指针会移动到指定的提交，但暂存区和工作区的代码修改会被保留。",
      "分支的HEAD指针、暂存区和工作区将完全回退到指定提交的状态。",
      "只会撤销指定的提交，并生成一个新的提交来记录这一操作。",
      "分支的HEAD指针和暂存区会回退，但工作区的代码修改会保留。"
    ],
    "correctAnswerIndex": 0,
    "explanation": "`--soft`是`reset`命令中最“温和”的选项。它只移动HEAD指针，意味着它撤销了提交记录，但所有在这些提交中的代码变更都会被保留在暂存区（Staging Area），你可以重新检查、修改后再次提交。",
    "source": "文档中「3.3 Reset 的常用选项」部分",
    "hint": "文档描述这个选项“仅修改 HEAD，保留暂存区和工作区的内容”。"

    "question": "你的同事在 `feature` 分支上修复了一个关键的线上bug，提交哈希为`3456789`。现在你需要立即将这个修复应用到 `master` 分支，但 `feature` 分支上还有其他未完成的功能。最合适的操作是什么？",
    "options": [
      "切换到 `master` 分支，然后执行 `git merge feature`。",
      "在 `feature` 分支上执行 `git reset --hard 3456789`。",
      "切换到 `master` 分支，然后执行 `git revert 3456789`。",
      "切换到 `master` 分支，然后执行 `git cherry-pick 3456789`。"
    ],
    "correctAnswerIndex": 3,
    "explanation": "这个场景正是`git cherry-pick`的典型应用。它允许你精确地“挑选”一个提交，并将其应用到另一个分支，而不会带上源分支的其他不相关的提交。这对于紧急修复或功能移植非常高效。",
    "source": "文档中「1.2 使用场景」和「1.4 实际案例」部分",

    "question": "在执行 `git cherry-pick` 命令时，如果 Git 提示存在冲突（conflict），你需要做什么来完成操作？",
    "options": [
      "执行 `git reset --hard` 来放弃这次操作。",
      "手动解决文件中的冲突，`git add` 标记已解决，然后执行 `git cherry-pick --continue`。",
      "立即执行 `git push --force` 来强制覆盖远程分支。",
      "删除本地分支并重新从远程拉取。"
    ],
    "correctAnswerIndex": 1,
    "explanation": "当 Git 无法自动合并更改时，就会发生冲突。此时，Git会暂停操作，等待用户手动编辑冲突文件。解决完毕后，通过 `git add` 告诉 Git 冲突已解决，最后用 `--continue` 选项让 `cherry-pick` 继续执行。",
